|Basic chaturaji set-up|
The Oxford Companion to Chess by David Hooper and Kenneth Whyld (New Edition, Oxford University Press 1992) does not contain a description of the game of Chaturaji. It does, however, have a short but interesting entry on "dice:"
dice, used long before ches for gambling purposes, and perhaps even earlir for divination. it has been conjectured, without supporting evidence, that a forerunner of chess may have involved the use of four-sided dice to determine which piece was to be moved [sounds like Chaturaji]. There ar equal grounds for the suggestion that the first form of proto-chess was an oracular ceremony involving dice and that these were discarded in order to create a game of skill.
